SAFETY

GENERAL SAFETY

The following are general farm

safety precautions that should be

part of your operating procedure for

all types of machinery.

1. Protect yourself.

When assembling, operating and servicing

machinery wear all the protective clothing

and personal safety devices that COULD be

necessary for the job at hand. Don't take

chances.

You may need:

· a hard hat.

· protective shoes with slip resistant soles.

· protective glasses or goggles.

· heavy gloves.

· wet weather gear.

· respirator or filter mask.

· hearing protection. Be aware that prolonged

exposure to loud noise can cause

impairment or loss of hearing. Wearing a

suitable hearing protective device such as

earmuffs (A) or earplugs (B) protects

against objectionable or loud noises.

2. Provide a first-aid kit for use in case of

emergencies.

3. Keep a fire extinguisher on the machine. Be

sure the extinguisher is properly maintained

and be familiar with its proper use.

4. Keep young children away from machinery

at all times.

5. Be aware that accidents often happen when

the operator is tired or in a hurry to get

finished. Take the time to consider the

safest way. Never ignore warning signs of

fatigue.

PROTECT YOURSELF

PROTECT AGAINST NOISE

BE PREPARED FOR EMERGENCIES

SAFETY

GENERAL SAFETY

(continued)

6. Wear close-fitting clothing and cover long

hair. Never wear dangling items such as

scarves or bracelets.

7. Keep hands, feet, clothing and hair away

from moving parts. Never attempt to clear

obstructions or objects from a machine

while the engine is running.

8. Keep all shields in place. Never alter or

remove safety equipment. Make sure

driveline guards can rotate independently of

the shaft and can telescope freely.

9. Use only service and repair parts made or

approved by the equipment manufacturer.

Substituted parts may not meet strength,

design, or safety requirements.

10. Do not modify the machine. Unauthorized

modifications may impair the function

and/or safety and affect machine life.

11. Stop engine and remove key from ignition

before leaving operator's seat for any

reason. A child or even a pet could engage

an idling machine.

12. Keep the area used for servicing machinery

clean and dry. Wet or oily floors are

slippery. Wet spots can be dangerous when

working with electrical equipment. Be sure

all electrical outlets and tools are properly

grounded.

13. Use adequate light for the job at hand.

14. Keep machinery clean. Straw and chaff on a

hot engine are a fire hazard. Do not allow oil

or grease to accumulate on service

platforms, ladders or controls. Clean

machines before storage.

15. Never use gasoline, naphtha or any volatile

material for cleaning purposes. These

materials may be toxic and/or flammable.

16. When storing machinery, cover sharp or

extending components to prevent injury

from accidental contact.

NEVER WEAR LOOSE

OR DANGLING CLOTHES

KEEP AWAY FROM MOVING PARTS

is suspended from lift cables only. Keep

hands clear of conditioner and header when

winching.

c. Be sure that upper mounting bolts are

securely tightened before installing or

removing lower mounting bolts. Hay

conditioner weighs approximately 730 lbs.

(330 kg) and will fall suddenly if lift system

becomes disengaged.

IMPORTANT: For ease of installation, detach

header from tractor before attaching hay

conditioner to header. See Windrower Tractor or

Adapter Operator's Manual.

1. To move conditioner, attach chain hooks to

conditioner side frames as shown (or to U-bolt

on top sheet if present) and lift with forklift.

Position hay conditioner behind header,

approximately in center of swath opening. Be

sure mounting hardware (A) (5/8 mounting bolt,

flatwasher, lockwasher and nut) is in place on

both sides.

NOTE: Watch clearance at gear case (B) and L/H

header leg (C).

If no means of moving the conditioner is available,

use the tractor to position the header as shown

below, then detach header from tractor.

a. Position tractor and header in front of hay

conditioner at angle shown below.

b. Check alignment of hay conditioner with tractor

to ensure sufficient clearance at (D), (E) & (F).

c. Slowly drive tractor straight back so the hay

conditioner is positioned as shown by dotted

lines.

d. Detach header from tractor and back away.

e. Manually rotate right side of hay conditioner so

winch cables can be installed.
